Application filed October 25,1906. Serial No. 340,587.

T0 @ZZ whom, it may concern.-

Be itknorvn that I, PABX ORRV HAYs, a citizen of the United States, residing at Grainesyille, in the county of Cooke and State of Texas, have invented certain new and useful improvements in Acetylene-Gas Generators, of which the following is a specification.

This invention relates to improvements in acetylene gas generators.

The invention con'iprises the production of a suitable frame., a receptacle' positioned Within said frame and a gas-bell positioned to reciprocate in said frame and partially in said receptacle. u

The invention further comprises the prodijction of a gasometer having a gas strainer and receiving. chamber positioned 'therein carbid lor the generation of gas, and means for collecting and holding said gas ready for distribution at a predetermined pressure at all times.

W'ith these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings :-l igure 1 represents avertical section through a gasgenerating device embodying the features of the present invention. Fig.' 2 is a vertical section taken through a gas generating device embodying the. features of the presentV invention, the gas-bell and mechanism connected therewith being shown in an elevated position.` Fig. 3 is a detail, sectional view of a receptacle and chute used for holding means for regulating the pressure in the gasa bell of the present invention. v

'ln acetylene gas generators the carbid is either dropped inte Water or Water is forced in contact with the carbid in order to generate gas and when contact is thus made, often times more gas is generated than desired, and also more than can be conveniently acco1n modated. W hen this occurs the pressure in the gas ygenerator increases considerably and ing the feed of the carbid or the water in or-V der to regulate the amount of gas generate. 6o and consequently regulate, to a certain `exa. tent, the pressure inthe Gas-bell ofthe generator. Means have also )een provided with. more or less success for filtering or straining the gas after the same has been generated 65 ,.f. and then holding the same in a com artment Y or receptacle under pressure ready 'or use.

This invention relates `to a device that is l adapted to accomplish the above desirable results, and like results by a simple mechan- 7o manufactured and notk isin that is easily easily gotten out of order. A

Referring more particularly tothe drawings, 1 indicates a frame of any suitable con` struction to which is secured a gasometer 2. 'i735 The gasometer 2 is provided With an outer tank 3 and an inner tank L-,vmade independently The easing 4 is adaptedto hold Water for use The Water in the tank or casing 4 is usually quite above the top row of holes of a small gas-dome 5 to be hereinafterv more fully described.` The tank 3 is adalpted to contain 85 if liquid of any kind, preferab y Water, land is usually filled almost entirely full so,that as the large gas-bell 6 reciprocates therein a Water seal will be continually provided for Ll y preventing from 'escaping' from the bell. 9o

Surrounding the tank 4 is any suitable number of packing rings, as 7, that are adapted to f prevent the gas-bell 6 from contacting with the receptacle 4, and also to normally hold'. the gas-bell 6 in a vertical rality of uprights as 7 are Vpreferably positioned 'between the gas-bell 6 andthe tank 3' and extends to any desirable distance above f the bell 6 for assisting in guiding the same in its movement.

Positioned upon the top of lico the gas-bell 6 and formed integral therewith j l 9 which is 105 Directly above the valve the chamber S. A small optningis left be- ,tween the lower edges of themembdr through which carbid is permitted toifeed vvdown upon the valve 9. In this wry? the. valve 9 1n operation is not compelled 'almost the entire amount of carbid `vn the S into 'the siriall gas-bell 5. `When the large bell 6 is lowered, as seen' in Fig. 1 of thedrawings, the valve 9 is raised-through the action of the rod 12"corning in contact with tlie bottom of the tank 4. In Fig. 1 of/ the draw? ings the bell 6 is shown as being in vits lowest position and the valve Q in its outermost position, but it will be evident 4that 1n case the bell is not lowered entirely to its lowest posi- -tion'it will yet allow the rod 1 2 to operate the valve 9 for permitting a small amount of carbid to feed into the small bell 5. After the carbid is -allowed to drop by gravity into the bell 5, it is arrested in its downward move ment by coming in contact with a wire net ting or screen 13 removably secured on the lower end thereof.

` used to firmly secure the screen 13 in place.

When the lower part of the bell 5 is in a position sufficiently near the bottom of the chamber 4, water will cover the netting 13 to a more or less extent, and as-the carbid is dro ped upon the netting it comes in contact wit the water and consequently evolves gas. If there is a considerable amount of 'gas already in the large bell 6, the water in the small bell 5 will usually be of no greatdepth and consequently the gas evolved will be produced slower and conse uently only a suflicient amount is evolvedior raising the bell 6 to such a position that sometimes the wire netting 13 will be entirely out of contact with the water in tank 4. When the small bell 5 is thus raised it will beevident that the carbid that is still therein undissolved will not dissolve or evolve the gas until sufiicient gas has been withdrawn Jfrom the gas-bell 6to permit .the wire netting 13 to descend into the water in the/tank 4, and consequently will permit. the carbid resting thereon to be dissolved.l In this way'only suflicient carbid will be dissolvedto hold the large bell 6 within certain limits and consequently hold the pressure of the gas substantially the same, although the volume contained in the gascmeter mayv vary slightly. `When considerable gas has been withdrawn from the large bell 6, the bell 6 will descend carrying with it all the mechanism secured thereto and will `tlie gas bell.

Il' for generated, the bell 6 will raise until the gas and thus insure against the displacement of In practice i have the apertures 15 and 16 normally below the water line in the tank 4 so that when t is preferably desirablel to.

carbid is dropped upon the screen 13 the gas evolved therefrom will ll the bell 5 and chamber 8, and'will inally force its way out through the apertures 15 and 16, and then pass upward through the water in the upper part o tank 4 into the large bell 6. As the f gas rises in the bell 6 it cornes in contact with a sieve or strainer 17 composed of cotton or any other desirable material for thoroughly straining and drying the gas before the same reaches the extreme top of the bell 6. Inarranging the bell 5 so as to compel thev gas generated therein to pass through the water it was designed that the passage of the gas through the water was for washing and cleaning and cooling the Same. After the gas has thus been cleaned and cooled, it is further cleaned and also dried by passing through the strainer 17 and finally when it reachesthe extreme'top of the bell 6 it is in condition for consumption andinay vbe removed theretrom through a valve 18 and a pipe 19. The ,strainer v17 is supportedl by means of a wire netting 20, preferably Jo'f-a coarse mesh, and -`s held in a compact yormfro by means of a wire 21 placed above the same. The wire 21 is adapted to keep the cotton 17 and the like from entirelyfilling IOO the' upper part of the bell 6. B'ythus us'ing the wire A21 to' hold the cotton 17 in a coniact form, a small chamber or receptacle 1s termed at the extreme top of the'bell 6in which the cleaned and dried gas is permitted to accumulate preparatory to consumption. As shown there is only one wire 21 used to lace, but it will be and hose connections 27 Ylor readily supplyn ing the water to the receptacle 4 in any position of the bell 6.

Mounted upon the top of the large bell 6 in any suitable manner is a receptacle 28 which is adapted to receivesmall particles, as for instance, shot or sand from a tank 29. The tank 29 is rigidly secured to the frame 1 and is provided with a hopper 30 and chute 31. Below the hopper 30 and preferably formed integral therewith is a sleeve 32 in which rcciprocates a plunger The vplunger 33 and the tank 28 are rigidly secured to the top of the bell 6 and are adapted to reciprocate therewith. When the bell 6 is lowered until the valve 9 opens the carbid is fed from chamber 8 and plunger 33 will be lowered and consequentlypermit material fromthe tank 29 to feed through o ening 34 into the hopper 30. As the carbi fed from the chamber 8 is dissolved, the weight of the bell 6 is decreasedand consequently the same requires less pressure to be held in its raised position. In order to compensate for this the plunger 33 is arranged to be forced upward through the ho per 30 when the bell 6 rises, and consequent y most of the material in the hopper 30 will be forced out and will pass down through chute 31 into the receptacle 2. The size of the hopper 30 and the plunger 33 is such as to automatically feed out material from tank 29 at such a weight as will approximately equal the weight of the carbid fed .from thev chamber 8. At each movement of the bell 6 when carbid-is fed -into tank 8, an equal amount of material will be fed from tank 29 and drop into the receptacle 28 and consequently the weight of the large bell 6 will be substantially the same at all times with the result that the gas'pressure therein will be automatically kept at an even pressure. It is also to be observed thatA when the carbid is dropped upon the screen 13 in the small bell 5 it comes in contact with t-he upper part or stratum of the water and consequently the purest contained in the tank 4. After the carbid has dissolved the sediments therefrom will descend by gravity 'to the bottom of tank'4 and leave the water in the upper part of the tank practically pure. In this way each new charge of carbid is permitted to contact with'substantially pure water and as a result more thoroughly dissolve and evolve readily the entire amount of gaseous matter contained thereiI'L Then lilliiig'the carbid chamber S the bell 6 is held elevated by means of any suitablev number of supporting hooks 37 that are preferably secured to the bell 6 at one end and having hooks formed upon the opposite end. W'hen it is desired to hold the bell 6 elevated the hooks are simply placed over the top of the tank 3. After the carbid chamber has been filled and the receptacle 23 emptied the hooks 37 are removedfroiii the tank andthe bell 6 is permitted to operate in th(` usual manner. i

A valvel 35 is provided at the chamber 8 through which excessive pressure may be permitted to esca e or if desirable the gas may be removed t crel'roiii for consumption. lt is also adapted for use in filling the chamber 8 with carbid. When the valve 35 is used for filling the chamber 5s it is made of a large size for accommodatingr the carbid. Another valve as 36, is provided in the bottom of tank 4 for removing the water and sediments from the carbid from said tank. 'lhe valve 36' maybe of any size and construction that will accom plish these purposes.
